Description

Technical Field

[0001] This application belongs to the field of display technology, and in particular relates to a light panel and display device. Background Technology

[0002] With the rapid development of display technology, Mini-LED display technology has emerged as a new display technology. Mini-LED displays are composed of hundreds of thousands or even millions of RGB light-emitting chips with a size of micrometers. After the RGB chips are prepared, they need to be transferred to the corresponding light board. Because of the large number of chips, the mass transfer has become a major challenge for Mini-LED displays, and it is even more complicated for ultra-large-size display devices.

[0003] Mass transfer methods mainly include flexible stamping, fluid self-assembly, precision pick-and-release, and laser release. Flexible stamping involves controlling the adhesion between the flexible stamp and the chip interface to pick up and release the chip. This process requires precise control of the stamp's movement speed and angle, which is challenging and requires an extremely flat chip substrate to avoid gaps between the stamp and the chip, reducing transfer efficiency. Fluid self-assembly places the chip and receiving substrate in a fluid-filled container, using fluid force to move the chip to the receiving position. This method requires special treatment of the chip and receiving substrate to create structural complementarity. Precision pick-and-release is categorized based on the applied force: electrostatic force, electromagnetic force, swing arm type, and needle-type. Electrostatic and electromagnetic forces utilize a transfer head with static electricity or magnetism to grasp the chip; once at the designated position, the static electricity or magnetism is removed, completing the chip release. Both of these methods require special chip treatment, increasing the risk of chip damage. Laser release uses laser irradiation of the release layer, causing a photothermal or photochemical reaction on the surface, causing the chip to peel off onto the receiving substrate.

[0004] However, the aforementioned mass transfer method can damage a large number of RGB LED chips or result in improper installation during the installation process, leading to low installation efficiency. Summary of the Invention

[0005] In view of this, embodiments of this application provide a lamp board and a display device to solve the technical problem of low installation efficiency of existing light-emitting chips.

[0006] In a first aspect, embodiments of this application provide a light panel, comprising:

[0007] The base has flow channels for fluid circulation;

[0008] The vibration mechanism includes multiple vibration units arranged in an array on the base. Each vibration unit includes a fixed part and a vibration part. The fixed part is connected to the base, and the vibration part is rotatably connected to the fixed part. The vibration part is used to drive the light-emitting unit to vibrate. The vibration unit also has a cavity that communicates with the flow channel. Each cavity in the vibration unit arranged side by side along the first direction is interconnected.

[0009] A driving mechanism is located on the side of the base away from the vibration unit. The driving mechanism is used to drive the fluid in the flow channel and the cavity to flow in one direction, causing the vibration part to vibrate, so that the light-emitting unit is positioned and fixed on the base.

[0010] In some embodiments, the base is further provided with a support unit, which is located above the vibration mechanism and is used to support and fix the light-emitting unit in a fixed position.

[0011] In some embodiments, the vibration unit further includes a first connecting portion and a second connecting portion located within the cavity, one end of the first connecting portion being connected to the fixed portion, and the other end of the first connecting portion being rotatably connected to the vibration unit;

[0012] The two ends of the second connecting part are respectively connected to the fixing part and the vibrating part through elastic elements;

[0013] When fluid enters the cavity from the flow channel, the fluid causes the elastic elements at both ends of the second connecting part to deform, causing the vibrating part to vibrate about the first connecting part as an axis, thereby causing the light-emitting unit located on the support unit to vibrate and then be positioned and fixed with the support unit.

[0014] In some embodiments, the first connecting portion is located at the middle of the vibrating portion and the fixing portion.

[0015] In some embodiments, multiple second connecting portions are provided, and the multiple second connecting portions are evenly distributed in the cavity.

[0016] In some embodiments, the cavity is formed between the fixing part, the vibrating part, and the first connecting part, the cavity including an inlet and an outlet, and elastic connecting members are provided at the inlet and the outlet;

[0017] The width of the inlet and the width of the outlet are smaller than the width of the flow channel;

[0018] The size of the inlet and the outlet is adjusted by the deformation of the elastic connector.

[0019] In some embodiments, the vibrating part is further provided with a power generation unit, which is connected to the drive mechanism and is used to provide power to the drive mechanism.

[0020] In some embodiments, a barrier unit is movably mounted on the side of the base to prevent the light-emitting unit from falling outside the base.

[0021] In some embodiments, a lifting unit for driving the enclosure unit to rise is further mounted on the base, the lifting unit comprising:

[0022] A booster is installed inside the base and is connected to the flow channel;

[0023] An injection head is connected to the booster, and the injection head has an injection channel inside;

[0024] When the fluid located in the flow channel enters the intensifier and is pressurized, it is ejected through the injection channel to lift the enclosure unit.

[0025] In some embodiments, the drive mechanism includes:

[0026] A fan, mounted on the base, is used to drive fluid to flow in the flow channel and the cavity.

[0027] In some embodiments, the drive structure further includes a one-way valve installed within the flow channel, the one-way valve being used to allow fluid located in the flow channel and the cavity to flow in one direction.

[0028] Secondly, embodiments of this application provide a display device, including:

[0029] The lamp panel described in the first aspect;

[0030] A light-emitting chip is located above the vibration unit; and

[0031] An encapsulation layer is disposed on the side of the light-emitting chip away from the vibration unit.

[0032] In some embodiments, a functional layer is provided between the light-emitting chip and the encapsulation layer, the functional layer including a polarizer and a filter layer.

[0033] The lamp board and display device provided in this application embodiment drive the fluid in the flow channel and cavity to flow unidirectionally through the driving mechanism, causing the vibrating part to vibrate, which in turn causes the light-emitting chip located above the vibrating part to vibrate, so that the light-emitting unit is positioned and fixed on the base. The array of vibrating units can install a large number of light-emitting units, and the lamp board after installation is part of the display device, thus greatly improving the installation efficiency of the display device. Furthermore, this application uses a small vibration method to achieve the positioning and fixing of the light-emitting unit, which is different from the existing technology that uses blowing and large-amplitude oscillation to move the light-emitting chip into the mounting slot. In this application embodiment, the vibrating part is vibrated by driving the fluid through the driving mechanism, and the vibration method is relatively gentle and will not cause damage to the light-emitting unit.

[0063] TFT (Thin Film Transistor);

[0064] OLED (Organic Light-Emitting Diode);

[0065] LED (Light-Emitting Diode).

[0066] The first aspect of this application provides a light panel, such as... Figure 1 , Figure 8 and Figure 9 As shown, it includes a base 10, a vibration mechanism, and a drive mechanism 30;

[0067] The base 10 has a flow channel 100 for fluid flow;

[0068] The vibration mechanism includes multiple vibration units 20 arrayed on the base 10. Each vibration unit 20 includes a fixed part 21 and a vibration part 22. The fixed part 21 is connected to the base 10, and the vibration part 22 is rotatably connected to the fixed part 21. The vibration part 22 is used to drive the light-emitting unit 80 to vibrate. The vibration unit 20 also has a cavity 200 that communicates with the flow channel 100. The cavities 200 in the vibration units 20 arranged side by side along the first direction are interconnected.

[0069] The driving mechanism 30 is located on the side of the base 10 away from the vibration unit 20. The driving mechanism 30 is used to drive the fluid in the flow channel 100 and cavity 200 to flow in one direction, thereby causing the vibration part 22 to vibrate, so that the light-emitting unit 80 is positioned and fixed on the base 10.

[0070] The lamp panel provided in this application embodiment uses a driving mechanism 30 to drive the fluid in the flow channel 100 and cavity 200 to flow unidirectionally, causing the vibrating part 22 to vibrate, which in turn causes the light-emitting chip 86 located above the vibrating part 22 to vibrate, so that the light-emitting unit 80 is positioned and fixed on the base 10. The array of vibrating units 20 can install a large number of light-emitting units 80, and the lamp panel after installation is part of the display device, thus greatly improving the installation efficiency of the display device. Furthermore, this application uses a small vibration method to achieve the positioning and fixing of the light-emitting unit 80, which is different from the prior art that uses blowing and large-amplitude oscillation to move the light-emitting chip 86 into the mounting slot. In this application embodiment, the driving mechanism 30 drives the fluid to vibrate the vibrating part 22, which is a gentler vibration method and will not cause damage to the light-emitting unit 80.

[0071] In applications, such as Figure 1 As shown, Figure 1The diagram shows a cross-sectional view of the lamp panel. The center of the base 10 is recessed inwards, and the periphery of the base 10 is higher than the center, forming a baffle. After installation, the baffle becomes the frame of the display device. In application, the drive mechanism 30 is located in the center of the base 10. This arrangement results in the center of the back of the final display device protruding outwards, which is more aesthetically pleasing. The drive mechanism 30 divides the flow channel 100 into two parts, driving fluid to flow unidirectionally within the flow channel 100 and the cavity 200. The fluid includes, but is not limited to, air, inert gas, etc.

[0072] In applications, such as Figure 1 As shown, the vibration unit 20 array is arranged on the base 10: that is, multiple vibration units 20 are arranged side by side along the first direction and the second direction. The first direction and the second direction are the length and width directions of the lamp panel (or display device), and the third direction is the thickness direction of the lamp panel (or display device). The cavities 200 of the vibration units 20 arranged side by side along the first direction are interconnected. This means that the cavities 200 of the vibration units 20 arranged side by side along the length or width direction of the lamp panel are interconnected and then connected to the flow channel 100. This ensures that the fluid flows within the cavities 200 of the flow channel 100, thereby providing driving force to the vibration part 22, causing the vibration part 22 to drive the light-emitting unit 80 to vibrate, thereby positioning and fixing the light-emitting unit 80 to the base 10, realizing the mass transfer and installation of the light-emitting unit 80.

[0073] In some embodiments, such as Figure 1 and Figure 4 As shown, the drive mechanism 30 includes a fan 31 mounted on the base 10, which drives fluid to flow within the flow channel 100 and the cavity 200. In some embodiments, the drive mechanism 30 further includes a one-way valve 32 mounted within the flow channel 100, which allows the fluid within the flow channel 100 and the cavity 200 to flow in one direction only.

[0074] In some embodiments, such as Figure 1 As shown, a support unit 40 is also provided on the base 10. The support unit 40 is located above the vibration mechanism and is used to support and fix the light-emitting unit 80 in position. In application, the support unit 40 is located above the vibration mechanism in several ways: First, there is a gap between the support unit 40 and the vibration mechanism, which provides space for the vibration unit 20 to vibrate, thereby facilitating the vibration of the light-emitting unit 80 located on the support unit 40, thus fixing the light-emitting unit 80 in position with the support unit; Second, the support unit 40 is in direct contact with the vibration mechanism, which helps to improve the stability of the light-emitting unit 80 after installation.

[0075] In applications, such as Figure 1and Figure 2 As shown, the support unit 40 includes a metal layer 43, a planarization layer, and a circuit layer 41 stacked sequentially. The metal layer 43 is located on the side closer to the vibration unit 20, and the circuit layer 41 is located on the side away from the vibration unit 20 (i.e., closer to the light-emitting unit 80). During the mass transfer installation of the light-emitting unit 80, the light-emitting unit 80 is in direct contact with the circuit layer 41, and the installation process is also achieved by vibrating the light-emitting unit 80 to connect it to the circuit layer 41.

[0076] The metal layer 43 is primarily used to form conductive paths, i.e., wiring or interconnect structures, and is a key component of the TFT (Thin Film Transistor). The metal layer 43 may include the following components: 1. A gate metal layer 43 forms the gate of the TFT, controlling whether current flows through the channel between the source and drain. 2. Data lines and scan lines are used to transmit signals to the TFT of each pixel. Data lines typically carry brightness information, while scan lines select which row of pixels should be activated. 3. Power lines provide the necessary voltage to the TFT and other components. In some embodiments, the metal layer 43 is generally made of materials such as aluminum, copper, molybdenum, and titanium; sometimes alloys are used to improve performance or reduce cost. This ensures fast and accurate signal transmission. The main purpose of the planarization layer is to make the surface smoother, thereby improving the quality and reliability of subsequent processes. Specific functions of the planarization layer include: reducing surface roughness, stress buffering, alleviating stress caused by differences in thermal expansion coefficients between different material layers, and preventing crack formation. It also has an insulating function; the planarization layer is typically a dielectric material that provides good insulation between different metal layers 43, preventing short circuits. For OLED displays, the planarization layer also helps to evenly distribute organic light-emitting materials, ensuring uniform light emission. Commonly used materials for planarization layers include polyimide, acrylic resin, and siloxane. These materials have good flowability and rigidity after curing, effectively filling unevenness in the underlying structure. The circuit layer 41 refers to the entirety containing all electronic components and interconnect structures; it is the core part for realizing display functions. The circuit layer 41 mainly includes integrated circuits for generating and processing electrical signals, converting them into a format suitable for display. In some embodiments, the circuit layer 41 may also include power management circuits, timing controllers, gamma correction circuits, etc., which work together to optimize image quality and system stability.

[0077] It should be noted that the vibration of the vibrating part 22 causes the light-emitting units 80 located on the support unit 40 to vibrate, thereby positioning and fixing the light-emitting units 80 to the support unit 40. The specific principle is as follows: When a large-scale transfer and installation of the light-emitting units 80 is required, the light-emitting units 80 are placed on the support unit 40 in a random order. Then, the driving mechanism 30 drives the fluid in the flow channel 100 and the cavity 200. The fluid flow causes the vibrating part 22 to vibrate, thereby causing the light-emitting units 80 on the support unit 40 to vibrate irregularly. This continues until the positioning structure on the light-emitting unit 80 connects with the support unit 40, thus completing the installation and transfer of the light-emitting units 80. The positioning structure on the light-emitting unit 80 includes, but is not limited to, magnetic components, such as electromagnets. It attracts the light-emitting units 80 to the metal or magnetic components on the support unit through magnetic attraction. This completes the positioning and fixing of the light-emitting units 80, ensuring the stability of subsequent installation and guaranteeing the display effect.

[0078] In some embodiments, such as Figure 1 and Figure 3 As shown, the vibration unit 20 also includes a first connecting part 23 and a second connecting part 24; both the first connecting part 23 and the second connecting part 24 are located inside the cavity 200, one end of the first connecting part 23 is connected to the fixing part 21, and the other end of the first connecting part 23 is rotatably connected to the vibration part 22.

[0079] The two ends of the second connecting part 24 are respectively connected to the fixing part 21 and the vibrating part 22 via elastic members 26;

[0080] When the fluid enters the cavity 200 from the flow channel 100, the fluid causes the elastic members 26 at both ends of the second connecting part 24 to deform, causing the vibrating part 22 to vibrate up and down about the first connecting part 23 as the axis, so as to drive the light-emitting unit 80 located on the support unit 40 to vibrate and then be positioned and fixed with the support unit 40.

[0081] In application, the first connecting part 23 is a connecting post. One end of the connecting post is fixed to the fixing part 21, and the other end of the connecting post is hinged to the vibrating part 22, so that both ends of the vibrating part 22 can rotate up and down about the hinge point of the connecting post. The vibrating part 22 exerts a force on the supporting unit 40, thereby causing the light-emitting unit 80 located on the supporting unit 40 to vibrate until the positioning structure on the light-emitting unit 80 is fixedly positioned with the supporting unit 40. To describe it more vividly, the two ends of the vibrating part 22 are like drumsticks, and the entire supporting unit 40 is like a drum. When the drumsticks rotate around the first connecting part 23, they strike the supporting unit 40 to make it vibrate, which in turn causes the light-emitting unit 80 located on the supporting unit 40 to vibrate.

[0082] In some embodiments, such as Figure 1 and Figure 3 As shown, the first connecting part 23 is located in the middle of the vibrating part 22 and the fixing part 21. This allows the vibrating part 22 to vibrate along the first connecting part 23 as the center line, so that both the left and right ends can vibrate, which helps to improve the efficiency of driving the vibrating part 22 to vibrate.

[0083] In application, the second connecting part 24 is a connecting rod, and both ends of the connecting rod are provided with elastic elements 26. The connecting rod is connected to the fixed part 21 and the vibrating part 22 through the elastic elements 26. This arrangement is to generate vortex-induced vibration when the fluid enters the cavity 200, so that the second connecting part 24 vibrates and drives the vibrating part 22 to vibrate up and down.

[0084] In some embodiments, such as Figure 3 As shown, the vibration unit 20 includes a fixed part 21, a vibration part 22, a first connecting part 23, and a plurality of second connecting parts 24. The vibration part 22 is located on the side of the fixed part 21 away from the base 10. A cavity 200 is formed between the fixed part 21 and the vibration part 22. An inlet 201 and an outlet 202 are respectively provided at the front and rear ends of the cavity 200. An elastic connector 25 is provided at both the inlet 201 and the outlet 202 to connect the fixed part 21 and the vibration part 22. One end of the first connecting part 23 is connected to the middle of the fixed part 21, and the other end of the first connecting part 23 is hinged to the vibration part 22. A plurality of second connecting parts 24 are evenly distributed in the cavity 200. An elastic member 26 is provided at both ends of the second connecting parts 24, thereby connecting them to the fixed part 21 and the vibration part 22. The specific principle of causing the vibrating part 22 to vibrate is as follows: When the driving mechanism 30 drives the fluid and the flow channel 100 enters the cavity 200, the fluid velocity is increased (specifically because the inlet 201 of the cavity 200 is relatively narrow, narrower than the flow channel 100 and the cavity 200). If the velocity is greater than 10 m / s, the Reynolds coefficient increases and turbulence is achieved. The second connecting part 24 (cylinder) generates vortex-induced vibration under the action of the flow field, thereby causing the vibrating part 22 to vibrate. In addition, the vibration amplitude and even the resonance state of the vibrating part 22 can be adjusted by changing the Young's modulus of the rod, the elastic constant K of the spring, and the fluid flow state, thereby achieving rapid installation.

[0085] In applications, the second connecting part 24 can be made of a material with a low Young's modulus, including rubber, low-density polyethylene, polypropylene, polyethylene terephthalate, polystyrene, nylon, titanium alloy, etc. This is beneficial for improving vortex-induced vibration efficiency, thereby improving the installation efficiency of the light-emitting unit 80.

[0086] In some embodiments, such as Figure 3As shown, a cavity 200 is formed between the fixing part 21, the vibration part 22 and the first connecting part 23. The cavity 200 includes an inlet 201 and an outlet 202, and an elastic connector 25 is provided at the inlet 201 and the outlet 202.

[0087] The size of the inlet 201 and outlet 202 can be adjusted by the deformation of the elastic connector 25. In this way, the flow rate of the fluid entering the cavity 200 can be adjusted, thereby improving the efficiency of vortex-induced vibration.

[0088] In this application, the width of the inlet 201 and the width of the outlet 202 are smaller than the width of the flow channel 100. This significantly increases the flow velocity when the fluid enters the cavity 200 from the flow channel 100.

[0089] In this application, the elastic element 26 and the elastic connector 25 are springs. Because springs are formed by bending and have a small contact area with the air, the contact area between the elastic element 26 and the elastic connector 25 and the fluid is reduced. This prevents significant obstruction during fluid flow, effectively improving the conversion efficiency of vortex-induced vibration.

[0090] In some embodiments, such as Figure 1 and Figure 3 As shown, the vibrating part 22 is also provided with a power generation unit 50, which is connected to the drive mechanism 30 and is used to provide power to the drive mechanism 30. In a specific embodiment, the power generation unit 50 is located at the connection between the first connecting part 23 and the vibrating part 22. The power generation unit 50 collects the alternating current generated by the left and right rotation around the axis during vibration and provides it to the drive mechanism 30 to maximize energy utilization.

[0091] In the application, the power generation unit 50 includes a rotor 52, a stator 51, wires 53, and a processing circuit 500. The rotor 52 is located at the hinge between the first connecting part 23 and the vibrating part 22, the stator 51 is arranged around the rotor 52, and the processing circuit 500 is located on the base 10. The stator 51 is connected to the processing circuit 500 through the wires 53. In some embodiments, each vibrating unit 20 is provided with a power generation unit 50. By converting the rotational vibration of multiple vibrating units 20 into electricity, and filtering and amplifying it through the processing circuit 500, power can be effectively supplied to the drive mechanism 30, thereby maximizing energy utilization.

[0092] The basic working principle of the generator set of stator 51 and rotor 52 is as follows:

[0093] The rotor 52 is the rotating part of the generator, typically consisting of one or more permanent magnets or electromagnetic coils energized with direct current to generate a strong magnetic field. The stator 51 is the stationary part, usually containing multiple conductors wound into coils. These coils are typically three-phase configured to generate three-phase alternating current. As the rotor 52 rotates, its magnetic field passes through the stator 51 coils. Due to the relative motion, the magnetic flux through the stator 51 coils changes, inducing an electromotive force (EMF) in the stator 51 coils according to Faraday's law of electromagnetic induction. The magnetic field generated by the rotor 52 periodically passes through the stator 51 coils as the rotor 52 rotates. Because the direction and strength of the magnetic field change with the position of the rotor 52, the magnetic flux through the stator 51 coils also changes continuously. According to Faraday's law of electromagnetic induction, this change in magnetic flux induces an EMF in the stator 51 coils. This EMF drives electrons to move within the stator 51 coils, thus forming a current. Because the rotor 52 rotates continuously, the change in magnetic flux is continuous and periodic, therefore the induced EMF is also periodic, thus forming alternating current.

[0094] In the application, the circuit diagram of processing circuit 500 is as follows: Figure 11 As shown, the alternating current generated at the points where the vibration parts 22 and the first connecting part 23 rotate is collected centrally through the circuit, generating an alternating voltage at the input of the circuit. The output voltage is increased by the transformer winding ratio, and the output voltage is rectified by capacitors C1 and C2 and transformers D1 and D2 to process the alternating current into direct current. Capacitors C1 and C2 discharge simultaneously, which further amplifies the driving current. Then, resistor R1, transistor T1, and capacitor C3 are used for filtering, and the current is further amplified by utilizing the characteristics of the transistor, providing sufficient power supply to the drive mechanism 30.

[0095] In some embodiments, such as Figure 4 and Figure 5 As shown, a retaining unit 60 is movably mounted on the side of the base 10. The retaining unit 60 is used to prevent the light-emitting unit 80 from falling outside the base 10. In this way, damage caused by the light-emitting unit 80 falling off during installation can be effectively avoided.

[0096] In some embodiments, such as Figures 4 to 6As shown, a lifting unit 70 for driving the enclosure unit 60 to rise is also installed on the base 10. In application, the lifting unit 70 includes a pressurizer 71 and a spray head 72; the pressurizer 71 is installed inside the base 10 and is connected to the flow channel 100; the spray head 72 is connected to the pressurizer 71 and has a spray channel 700 inside; when the fluid in the flow channel 100 enters the pressurizer 71 and is pressurized, it is sprayed out through the spray channel 700 to lift the enclosure unit 60. Thus, both the lifting unit 70 and the vibration unit 20 work by driving the fluid flow through the drive mechanism 30. In other words, before installing the light-emitting unit 80, the lifting unit 70 pressurizes the fluid and then lifts the enclosure unit 60 through the spray channel 700, thereby providing the light-emitting unit 80 with a high physical protection on all sides and preventing the light-emitting unit 80 from falling during vibration. During the installation of the light-emitting unit 80, the vibration unit 20 drives the fluid through the drive mechanism 30 to generate vortex-induced vibration, which in turn causes the light-emitting unit 80 to vibrate and achieve positioning and fixation.

[0097] In application, the enclosure unit 60 is movably mounted on the side of the base 10. A guide member 61 is provided on the pressurizer 71, and the enclosure unit 60 slides in conjunction with the guide member 61. When the enclosure unit 60 needs to be lifted, the drive mechanism 30 drives fluid into the pressurizer 71, pressurizes it, and then sprays it onto the enclosure unit 60, thus lifting it. After installation, the pressurizer 71 stops pressurizing, and the gas returns to the flow channel 100 for use as a heat dissipation medium. The guide member 61 can be a slide rail and slider, or a pulley and groove. Anything that allows the enclosure unit 60 to move along the side of the base 10 is acceptable. In some embodiments, when the installation of the light-emitting unit 80 is completed and the lifting unit 70 is no longer needed to lift the enclosure unit 60, the enclosure unit 60 needs to be limited. A locking buckle 11 is also provided on the outside of the base 10 to lock the enclosure unit 60 to the base 10.

[0098] In some embodiments, the light-emitting unit 80 refers to the light-emitting unit 80 in a light-emitting diode (LED) and an organic light-emitting diode (OLED) used in display technology. It has various structural types, including but not limited to traditional structures, vertical structures, and thin-film structures in LEDs, or small-molecule, polymer, top-emitting, bottom-emitting, and multilayer structures in OLEDs; or Micro-LED structures, quantum dot structures, etc. This application uses a quantum dot structure light-emitting unit 80 as an example for illustration. Figure 7As shown, the light-emitting unit 80 includes a protective layer 85, a reflective cup 82, and phosphor 81 stacked sequentially. A light-emitting chip 86 is also located at the bottom of the reflective cup 82. In application, the reflective cup 82 is designed to concentrate as much light emitted from the light-emitting chip 86 as possible forward, reducing lateral scattering and thus improving light output efficiency. It also provides physical protection against damage to the light-emitting chip 86 from the external environment. The material of the reflective cup 82 has good thermal conductivity, which helps to conduct heat away from the light-emitting chip 86, improving heat dissipation. Figure 7 As shown, the reflector cup 82 is a bowl-shaped or conical structure with its inner surface coated with a highly reflective material (such as aluminum or silver). The light-emitting chip 86 is located at the bottom center of the reflector cup 82, ensuring that the emitted light is collected and guided by the reflector cup 82 to the maximum extent. It is the element that actually generates light and is made of semiconductor materials (such as gallium nitride used in blue LEDs). Depending on the design, the light-emitting chip 86 can directly emit visible light (such as blue or green light) or emit ultraviolet light to excite the phosphor 81. The phosphor 81 is typically coated on the inner surface of the reflector cup 82 or directly overlaid on the light-emitting chip 86, forming a thin phosphor 81 coating. For blue LEDs, the phosphor 81 can absorb some blue light and re-emit other wavelengths of light (such as yellow light), generating white light by mixing blue and yellow light. This method is widely used in the manufacture of white LEDs. By selecting different combinations of phosphors 81, the color temperature and color rendering index of the output light can be adjusted to meet the needs of various lighting and display applications. The phosphor layer 81 helps to homogenize light, reduce light spots and shadows, and make the light output softer and smoother. The protective layer 85 typically covers the outermost layer of the reflector cup 82 and the phosphor layer 81, forming a sealed encapsulation structure. The protective layer 85 prevents moisture and humidity from entering the interior, avoiding moisture-induced failure of the phosphor 81 and the light-emitting chip 86. The material of the protective layer 85 has UV-resistant properties, preventing the aging effects of ultraviolet light on the phosphor 81 and other components. It provides additional physical protection against damage to the light-emitting device from external impacts and scratches.

[0099] In some embodiments, a positioning structure for positioning and fixing the light-emitting unit 80 and the support unit 40 is provided between the protective layer 85 and the reflective cup 82. The positioning structure includes an electromagnetic layer 84 and a wireless coil layer 83. When the light-emitting unit 80 and the support unit 40 are aligned, the wireless coil layer 83 in the light-emitting unit 80 is energized, so that the electromagnetic layer 84 generates magnetic force to conduct electricity, thereby attracting the metal layer 43 in the support unit 40 to achieve installation and fixation.

[0100] like Figure 8 , Figure 9 as well as Figure 10 The diagram shows a schematic of the process of installing the light-emitting unit 80 onto the lamp panel. Figure 8As shown, before the light-emitting unit 80 is installed, the locking buckle 11 on the outside of the base 10 is in the unlocked state. At this time, the drive mechanism 30 drives the fluid to flow, and the fluid enters the booster 71 to be pressurized, thereby lifting the enclosure unit 60 to prevent the light-emitting unit 80 from falling out of the base 10 due to vibration during the subsequent installation process. During the installation of the light-emitting unit 80, the fluid enters the cavity 200 of the vibration unit 20, causing the vibration part 22 to vibrate, thereby striking the support unit 40 to make the light-emitting unit 80 located on the support unit 40 vibrate, so as to achieve alignment and fixation.

[0101] like Figure 9 and Figure 10 As shown, after installation, pressing down on the enclosure unit 60 locks the enclosure unit 60 with the locking buckle 11 on the outside of the base 10; the booster 71 stops working, and the gas returns to the flow channel 100 as a heat dissipation medium; the electromagnetic layer 84 of the light-emitting unit 80 is magnetically fixed to the metal layer 43 in the support unit 40; the rotation generated by the vibration part 22 is collected by the power generation unit 50 and used to drive the gas flow of the drive mechanism 30 as a power source for subsequent heat dissipation, thus effectively improving the energy utilization rate.

[0102] This application embodiment also provides a display device, as shown in 12, including the lamp board, light-emitting chip 86 and encapsulation layer 90 described in the first aspect;

[0103] The light-emitting chip 86 is located above the vibration unit 20;

[0104] The encapsulation layer 90 is located on the side of the light-emitting chip 86 away from the vibration unit 20.

[0105] The display device provided in this application embodiment has all the beneficial effects described in the first aspect because it has the lamp board described in the first aspect. The display device provided in this application embodiment can solve the problem of mass transfer of the light-emitting unit 8050, and the installation can be completed synchronously using the heat dissipation device of the display device.

[0106] In some embodiments, such as Figure 12 As shown, a functional layer 900 is also provided between the encapsulation layer 90 and the light-emitting unit 80. The functional layer 900 includes, but is not limited to, a polarizer 901, a filter 902, and a thin-film transistor 903. The thin-film transistor acts as a switch, controlling the brightness and color of each pixel. The lower polarizer 901 is placed below the thin-film transistor 903. Its function is to convert the unpolarized light emitted by reflected light (for some types of OLEDs) into linearly polarized light. Different colors are displayed by passing through the corresponding filter 902. The upper polarizer 901 is installed on the top layer, covering the color filter 902. The upper polarizer 901 works in conjunction with the lower polarizer 901 to ensure that only polarized light in a specific direction can pass through and ultimately reach the viewer's eye.

[0107] The lamp board and display device provided in this application embodiment ingeniously utilize the heat dissipation device (i.e., fan 31) of the display device in the installation process of the light-emitting unit 80. Specifically, it includes:

[0108] Before installing the light-emitting unit 80, the fan 31 drives the airflow to raise the two side enclosure units 60 to facilitate the subsequent installation of the light-emitting unit 80 and prevent the light-emitting unit 80 from vibrating and falling off.

[0109] During the installation of the light-emitting unit 80, the driving gas continues to cause the second connecting part 24 to drive the vibrating part 22 to vibrate, thereby causing the light-emitting unit 80 to vibrate and complete the positioning and fixing of the light-emitting unit 80.

[0110] After the light-emitting unit 80 is installed, the fluid located in the flow channel 100 and cavity 200 serves as a heat dissipation medium for the display device.
